Fibroadenoma of Ectopic Breast Tissue - A Case Report

Fibroadenomas of the breast are highly common among females whereas fibroadenomas of ectopic breast tissue, which can occur anywhere along the early ‘milk lines' of breast development are a rare occurrence. We report the case of a 38 year old lady who presented to us with a firm, right axillary swelling of more than a year. The FNAC of the swelling turned out to be axillary fibroadenoma for which an excision biopsy was done and the post operative histopathological diagnosis turned out to be the same. Ectopic Breast tissues can occur anywhere along the embryonic milk lines but has also been reported to be found in the face, vulva, anus and foot. It can occur as just supernumerary nipples or as polymastia or in other forms. Any abnormalities arising from ectopic breast tissue can be evaluated using mammogram, cytology and ultra sonogram that are also used for diagnosis of pathologies of normal breast. The treatment of asymptomatic benign lesions of ectopic breast tissue is mainly psychological assurance and repeated follow up whereas in symptomatic patients surgery is the best treatment option.
